CVE-2026-35361: Improper Preservation of Permissions

The mknod utility in uutils coreutils fails to handle security labels atomically by creating device nodes before setting the SELinux context. If labeling fails, the utility attempts cleanup using std::fs::removedir, which cannot remove device nodes or FIFOs. This leaves mislabeled nodes behind wi...

CVE-2026-35381: Incorrect Provision of Specified Functionality

A logic error in the cut utility of uutils coreutils causes the utility to ignore the -s only-delimited flag when using the -z null-terminated and -d '' empty delimiter options together. The implementation incorrectly routes this specific combination through a specialized newline-delimiter code...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. There is a security vulnerability in uutils coreutils, which stems from a logical error in the cut command. When the -z and -d options are used simultaneously, the -s flag is ignored, potentially leadi...

CVE-2026-35344: Unchecked Return Value

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directorie...

CVE-2026-35345: Time-of-check Time-of-use (TOCTOU) Race Condition

A vulnerability in the tail utility of uutils coreutils allows for the exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting the...

CVE-2026-35340: Incorrect Check of Function Return Value

A flaw in the ChownExecutor used by uutils coreutils chown and chgrp causes the utilities to return an incorrect exit code during recursive operations. The final exit code is determined only by the last file processed. If the last operation succeeds, the command returns 0 even if earlier ownershi...

CVE-2026-35364: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mv utility of uutils coreutils during cross-device operations. The utility removes the destination path before recreating it through a copy operation. A local attacker with write access to the destination directory can exploit thi...

CVE-2026-35374: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the split utility of uutils coreutils. The program attempts to prevent data loss by checking for identity between input and output files using their file paths before initiating the split operation. However, the utility subsequently...

CVE-2026-35377: Improper Input Validation

A logic error in the env utility of uutils coreutils causes a failure to correctly parse command-line arguments when utilizing the -S split-string option. In GNU env, backslashes within single quotes are treated literally with the exceptions of \ and '. However, the uutils implementation...

CVE-2026-35359: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the ONOFOLLOW flag. An attacker with...

CVE-2026-35360: Time-of-check Time-of-use (TOCTOU) Race Condition

The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create, which internally uses OTRUNC. An attacker can exploit this window to create ...

CVE-2026-35351: Improper Preservation of Permissions

The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and...

CVE-2026-35352: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO for a symbolic link...

CVE-2026-35354: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the mv utility of uutils coreutils during cross-device moves. The extended attribute xattr preservation logic uses multiple path-based system calls that perform fresh path-to-inode lookups for each operation. A local attacker with writ...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. uutils coreutils has a security vulnerability, which stems from a logical error in the ln function. This vulnerability could allow local attackers to manipulate existing symbolic links, redirecting fil...

PT-2026-34474

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description A flaw in the chmod utility allows users to bypass the --preserve-root safety mechanism. The implementation validates if the target path is literally '/', but fails to canonicalize t...

uutils coreutils: Input validation error vulnerability

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. uutils coreutils has a vulnerability related to input validation errors. This vulnerability stems from a cut logic error, which incorrectly interprets two-byte literal strings as empty delimiters. This...

PT-2026-34516

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description A logic error in the cut utility causes the program to incorrectly interpret the literal two-byte string '' two single quotes as an empty delimiter. The implementation mistakenly map...

CVE-2026-35346: Improper Handling of Unicode Encoding

The comm utility in uutils coreutils silently corrupts data by performing lossy UTF-8 conversion on all output lines. The implementation uses String::fromutf8lossy, which replaces invalid UTF-8 byte sequences with the Unicode replacement character U+FFFD. This behavior differs from GNU comm, whic...

CVE-2026-35342: Insecure Temporary File

The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the...
